@alex3kov -- I think you mean the question as

"""
Since this behaviour will not change in future versions of Windows 7 / Windows 
Server 2008 R2, ...
"""

because, again, the problem is not in OVMF but in the Windows guest.

QEMU cannot be expected to recognize (guest OS, guest firmware, hw
config) combinations that might not work. That's not QEMU's business.

Such (automatic or semi-automatic) config tweaks belong to the
management layer. If you use virt-manager or virt-install to create your
guest, and select the guest OS type correctly (or let virt-manager /
virt-install recognize the guest type from a signature of the installer
ISO, which I believe is implemented with the help of libosinfo), then
virt-manager / virt-install will automatically disable Hyper-V
enlightments for you. This is what
https://bugzilla.redhat.com/show_bug.cgi?id=1185253 was about, which I
referenced here earlier.

The virt-manager change is <https://github.com/virt-manager/virt-
manager/commit/cbba1c4dd3815e3981d3b315bf28d1018f838702>.

So, the answer to your question is to use libvirt and its tools (which
is recommended anyway). Thanks.

(In general, I have no idea why large groups of users keep struggling
with QEMU command lines, when the interface that libvirt provides is
just so much better and easier for production use. The reason I always
recommend libvirt is not because I'm an RH zealot, the reason I
recommend it is that libvirt adds *actual value*, even for the
individual, interactive user.)

  When I boot my domain with windows2008 iso, the kvm was caught in
  endless interrupt. I enable trace on my host and I got this.
